Biomechanics! Help from anyone please...someone medical??

Hopefully someone can help me! I'm really confused about biomechanics!

I'll get back to my confusions later but at the moment I am doing an assignment and I don't know whether the question is just badly worded or i'm not getting it but the question says

Draw a diagram to represent the three types of levers...do you think it really means 3 diagrams or is there some way of doing a diagram showing all 3??

I don't understand :(

Help please???

I'm going to guess badly worded, and you need three, but it's been almost four years since I studied biomech.

I googled to try and refresh my memry, but the image I got it three separate diagrams (1st /2nd / 3rd class)

Hope someone else has got better information.

Thanks! I thought it must just be badly worded :wall:

I am really, really hating studying this by correspondence :computer:
